Rethinking launch from the ground up.

OUR MISSION

Rockets carry too much complexity into flight.
Longshot is moving more of the fuel and systems onto the ground.
‍
Building a reusable and cheaper accelerator infrastructure for space access and hypersonics.

OUR VISION

A human future in space needs a new way in.

Access has always shaped what humanity can build next. Longshot is working towards a future where reaching space is no longer limited by the cost, complexity, and cadence of traditional launch.

THE TEAM

Built for one of aerospace’s hardest infrastructure problems, Longshot combines engineering, operations, and government experience to move high-speed testing and future launch access forward.
